Hello Project summary ================= ptnet is a new multi-queue paravirtualized device that builds on ptnetmap to allow VMs to exchange TCP traffic at 20 Gbps, while still offering the same ptnetmap performance (10-100 Mpps) to native netmap applications. The purpose of this SOC project is to write a ptnet driver for FreeBSD and a corresponding device model for the bhyve hypervisor. Status update for week 11 =================== In this week I've written the ptnet device model emulation. Most of the functionalities have been implemented (the registers and the interaction with netmap backend). Next week I will do extensive testing of the ptnet driver over bhyve, bug fixing and performance evaluation.
